Nat Collins is this week's guest, Nat is a physical therapist, runner, running coach, 2.49 marathoner, and certified orthopedic specialist. The mindset to run ultramarathons is about more than pushing the limits. It’s making wise decisions in training, recovery, and gear. 

Nat ran track in 7th grade and quit after four day because he hated running. But, when he was in high school, a couple of his classmates convinced him to start running as a way to stay in shape.
